NXP Semiconductors MK20DN128VMP5

Overview

MK20DN128VMP5 from NXP (formerly Freescale) is a 32-bit ARM Cortex-M4 core microcontroller with DSP extensions, designed for embedded control applications requiring real-time processing, low-power operation, and integrated analog/peripheral functionality. It delivers 1.25 Dhrystone MIPS/MHz at 50 MHz, features 128 KB program flash, 16 KB RAM, and operates across –40 to 105°C in a 64-pin MAPBGA package.

For engineers reviewing the MK20DN128VMP5 datasheet, MK20DN128VMP5 pinout, MK20DN128VMP5 application, or MK20DN128VMP5 equivalent, key selection criteria include its 50 MHz Cortex-M4 performance, FlexMemory capability (not present in this variant), USB On-The-Go support, 16-bit SAR ADC, and multi-mode low-power architecture optimized for industrial sensing and motor control.

Technical Context

The MK20DN128VMP5 implements an ARM Cortex-M4 core with hardware DSP instructions and no FPU, operating up to 50 MHz. Its clock system includes a 3–32 MHz crystal oscillator, 32 kHz RTC oscillator, and a multi-purpose clock generator supporting multiple PLL and internal oscillator modes including FEI, FBE, and BLPE.

It integrates a 16-bit SAR ADC with configurable resolution and sampling rate, two analog comparators each with a 6-bit DAC and programmable reference, and eight-channel PWM/timer subsystems supporting motor control. Communication interfaces include USB full-/low-speed OTG with on-chip transceiver, three UARTs, SPI, I²C, and I²S - all accessible via flexible pin multiplexing in the 64-pin MAPBGA package.

FAQ

What is the maximum operating frequency of the MK20DN128VMP5?

The MK20DN128VMP5 operates at a maximum core/system clock frequency of 50 MHz. This is achieved using the internal PLL driven by the main crystal oscillator (3–32 MHz) or internal reference clock. The 50 MHz rating applies across the full –40 to 105°C ambient temperature range and 1.71–3.6 V supply voltage, as verified in the K20P64M50SF0 datasheet Rev. 4.

Does the MK20DN128VMP5 include FlexMemory?

No, the MK20DN128VMP5 does not include FlexMemory. The 'N' in the part number denotes "program flash only", distinguishing it from 'X' variants like MK20DX128VMP5 which integrate 32 KB FlexNVM and 2 KB FlexRAM. All flash memory in MK20DN128VMP5 is executable program flash - no portion is configurable as EEPROM or data flash.

What package type is used for the MK20DN128VMP5?

The MK20DN128VMP5 uses a 64-pin MAPBGA package (5 mm × 5 mm, 0.5 mm pitch), identified by 'MP' in the part number. This fine-pitch ball grid array supports high I/O density and thermal performance in compact industrial and automotive modules, with moisture sensitivity level (MSL) 3 per J-STD-020.

Which USB speed modes does the MK20DN128VMP5 support?

The MK20DN128VMP5 supports both full-speed (12 Mbps) and low-speed (1.5 Mbps) USB operation via its integrated On-The-Go controller and on-chip transceiver. Full-speed mode requires the system clock to be ≥20 MHz, as specified in the K20P64M50SF0 datasheet Section 5.3.1. No external PHY is needed, reducing bill-of-materials and layout complexity.

What is the ADC resolution and key specification of the MK20DN128VMP5?

The MK20DN128VMP5 features a 16-bit successive approximation register (SAR) ADC with configurable conversion speed and resolution. It supports up to 16 single-ended or 8 differential input channels, with typical SNR >86 dB and integral nonlinearity (INL) ±1.5 LSB - enabling high-fidelity sensor measurements in industrial and medical applications.
